Hey! I just got a unit with this same software but the AC doesn’t cool. It’s just hot air that comes out. Did you face the same issue? I tried your steps as well and I have the same canbus.
So I found out what to do when you do all of what he said. Go in factory settings and click on physical buttons study once there click on power and your a.c will come on.
I have a question, I’m also having problem with my hiworld canbus, but I have a 08 civic coupe. I don’t know where to connect the canbus once I plug it in but it’s like a part is missing
